Nigel,"I'm fairly sure it's a software issue as the same problem exists when running all hardware at stock settings. "What software has the issue?"the same problem exists when running all hardware at stock settings"Does this mean FSX with low sliders (default setup), no time acceleration, no purchased scenery or other 3rd party software, stock FSX aircraft and no overclocking?Because you previously mentioned (as an example)."Where I am still get a problem is with using the FS Recorder "Instant Replay" which is a real big problem for me because I'm trying to make a few nice flight movies. Sometimes it's works great... other times it causes the black screen or other graphics issues."

I just had another problem after using 8 x time simulation whish is simulair the black screen i have sometimes , my cockpit dessapeared and so did my aircraft in external view. its kind of frustrating when you were halfway of a flight that is well over 1600 nm and i,m only flying in europe , I can imagine it woule be ever more frustrating when flying the 747 from europe to the states for example. But i have no overclocked my computer and my computer can handle FSX pmgd just fine . I think its a bug with the pmgd 737 ngx software because i never had the problem with the stock aircraft in FSX.Oscar Klein

Nigel,If you do not use time acceleration and do not overclock your PC is PMDGNGX and FSX ok?"I was able to fly the PMDG for about a week or so with no problems at all".Right. I owned a computer repair company ... IMO, some of your PC components are ... well, stressed. That is why I asked about ... overclocking.Anyway, IMO, you need to take another look at you total system configuration (hardwar/software/heat/maxed out settings).

My pc isnt overclocked and i have checked the temperatue and my overal system to see if my pc is stressed and its not but still i get the same problem as Nigel.I think it doesnt have anything to do with the system is a a pmdg software issue i think , and its an anoyying one.

What is your name?

Oscar,"I think it doesnt have anything to do with the system is a a pmdg software issue".You know, it could be true.But, count how many pilots are reporting this problem.

Well whatever is the problem that causes it it still is extremly Irritating . On one flight it can work without any problems , and then on another all of a sudden the black screen ruins it.I just flew all the wat from Greece to londed gatwich and when i landed and was on the taxi way and wanted to end the FX passanger flight guess what , BLACK SCREEN !! (parts of the cockpit dissapeared first) Now i flew one and a half our in real time (it was about 3 hours game time), AND I didnt get any credit for in in fspassanger because i had a freakin black screen and fsx was all messed up and i could not acces the menu bar anymore. I waisted anther hour and a half of my time because of the black screen and i,m starting to loose hope now. Its just no fun flying knowing that any moment it can all be over bacause you get the black screen for no apparent reason. Oscar Klein

I think I've found the problem... but i'm unsure how to fix it.FSRecorder (posibly both FSRecorder and PMDG NGX combined) didn't like my bufferpools settings whcih were:[bufferpools]UsePools=0 RejectThreshold=102400PoolSize=2097152I changed the settings to this: [bufferpools]poolsize=490000000 After changing the Bufferpools... everything worked great. But I'm stuck with a decision. The previous bufferpools made FSX and PMDG run very smoothly for my system but at the cost of blackscreens when using FSRecorder, etc.The bufferpools I'm currently using cause no blackscreens at all but there's a noticable drop in smoothness. I may have to just switch between bufferpools when flying for fun and flying/making videos.The vid card I have is an ati 5870 1gb. I don't know a hell of a lot about bufferpools but I might try playing around with the parameters a bit and see what I can get away with (after backing-up ofcourse). Thx for the help Vonmar. It was your sugestion to have a look at the whole system configuration that helped me find the problem.

I doubt that this could be the problem to be IMHO , I had the problems before i installed FSrecorder (i just installed it yesterday) and many people use fsrecorder to put up tons of pmdg 737ngx movies on youtube , so it would mean that they should have the same problem. I think its only a matter time before you get another black screen , but offcourse i you wont.Oscar Klein

Yes true. But they may have used different Bufferpools settings or no Bufferpools tweaks at all, or the same settings with different hardware, etc.Either way, it's working ok at the moment. I'll post again if (hopefully not when) the problem comes back.

well i hope it solved the problem for you... I still have the problem and i never know when i reacht my destination without the blackscreen.

Oscar,You need to try to remember to sign your posts .. or they will get erased from this forum!What are your PC OS specs.?What is the path to your FSX files?Which version of FSX are you using?What hardware / software do you have runnung when FSX is running?

My PC OS specs are:AMD Phenom™ 9650 Quad-Core Processor2.3 GHz Performance Rated at: 4.60 GHz3.5 GB of ramMicrosoft Windows Vista Home Premium Edition Service Pack 2 (build 6002), 32-bitATI Radeon HD 4600 Series withg 2,3 GB video ram44.9 GB of disk spaceMy path to fsx is h: progam files / microsof games / flight simulator xI norrmaly close everything that is not needed to run the game , i have the logitech software running for my joystick but that about it.I had another grafics glitch after acclerating time , when i decalerated time all but my middle mfg turned black as if they were turned of or without juice , but when i clicked them with the mouse to inflate teh mfd they seemed to be working, but only when i clicked them so they still showed up black in the screen intself , after that i accerated time and decallerated to make my aproach and guess what , my grafics were all screwed up again. There are flights when everything goes as planned but on the next flight i get these problems sometimes 3 times in one session.Oscar Klein.

Oscar,What version of FSX are you using?You do not have any other software running with FSX .. no weather program, no scenery etc, just default FSX and PMDGNGX?

AFAIK, only 8x Max - should be used in FSX with a complex add-on such as NGX or MD-11.Do you drop from 8X to 4X first, rather than from 8x to 1x.?

I have FSX acceration (sorry i forgot to mentions this ) and pmdgngx , fspassanger and a couple days ago installed fsrecorder and the aes basepack demoversion . But the problems existed before installing fsrecorder and the aes basepack.Oscar Klein

Dear all, for me the same problem untill last week when I updated my ram with an extra 4mb (2x2mb). My ram total is now 8mb and seems to be working well, especcially for the ngx. Before the upgrade I had:fully distorted screen after switching eye-points, missing and/or partly transparant virtual cockpit, black screen, frozen game wich only could be stopped with ctrl/alt/del. I have a logitech G19 game keyboard with a used ram indicator.Before the upgrade when everything was loaded for the sim the indicator was almost compleet to the right. Sometimes I got the famous "not enough memory" announcement and I had to start all over again. As an indicator how critical it was: when fx loaded with the ngx and I only just started vlc player the game crashed. With my 8mb the ram indicator on the G19 is now a little bit OVER the half. Thus indicating how "heavy" the ngx is. I have tested the system while in flight changing screens/eyepoint and even swich several time from full view to windowed view and swiching to the map, no problemo so far... For me it was worth the 60 euro's.Kind regards from the Netherlands,Mark Carrickmy system specs: old stuff

Well i only use 8x time acceration max because the pmdg manual said so. but i go from 8x to 1x most of the timeOscar Klein
